Project 2_Creating a 3D rendered model for a Residential Building in AutoCad

AIM:Create a 3 dimensional model of the residential building with a rendered view.

INTRODUCTION:

The process of creating any surface of an object in three dimensions by using special software is called 3D modeling. A 3D model can also be represented as a two-dimensional image by using the 3D rendering process.

types of modeling:

• Wireframe modeling is useful for initial design iterations and as reference geometry, serving as a 3D framework for subsequent modeling or modification.
• Surface modeling offers fine control over curved surfaces for precise manipulation and analysis.
• Solid modeling is efficient to use, easy to combine primitives and extruded profiles, and offers mass properties and sectioning capabilities.

ues of 3D modeling views:

• change between different visual styles such as Conceptual, Realistic and X-Ray
• Switch between parallel and perspective projection
• Choose between standard preset views such as Top, Front and isometric view.

command in 3D modleing:

• extrude
• box-box,cylinder,cone.
• region
• boundry
• slice
• sweep
• loft
• revolve
• union
• subtract
• intersect
• extrude faces
• separate
• section plane
• UCS
• camera
• materials browser
• rendering

PROCEDURE:

• open autocad 2021 file and select impherical.
• set the units to engineering with precision 0'0.0".
• set the limax as 100',100'.
• zoom command and set all.
• set the view to top,keep ortho and osnap ON.
• plan the ground floor plan fo area 21'9"x43'8".
• exterior wall thickness be 9" and interior thickness 6".
• bedrrom dimension-13'x10',kitchen-6.5'x7'8",toilet-5.5'x5'.
• dinning-13'4"x13',ver/first floor bedroom-12.5'x12'7".
• door 1 D1- 3'x6.8',D2-2'x6'.
• window diemsion W1-4'x4'6".staircase window dimension-4'10"x6'.

• for elevation,parapet wall be 3' height.
• plinth level be 2' and height of buildig from plinth beam is 22'.
• gate dimension be 9'2"x6'8".

• make layers for wal,window,door.
• remove the dimension and text.
• enter boundry command and make region keeping wall layer as current.

• extrude the the wall upto 10'.

• set the view and same it.

• also enter UCS world nd set the icon and save the usc in usc maneger command.

• for door and window make rectangle in window layer,make it a region using boundary commandand copy to heights of silllevel and top.
• now extrude the recatngel to silllevel and top rectangle downwards.

• repeat the same for first floor also.
• now for making window frame,panel and glass.
• copy the elevation and make a group of one copy.
• move the group at plan section and rotate in YZ axis at 90 degree.

• from a copy of elevation,use boundry and subtact command.
• make a region of frame and subtact from smaller rectangle.
• similarly for next rectangle and last for glass.
• similar procedure for door frame and staircase window also.
• after making region extrude each recatngle of window in -ve y-axis.
• similarly for doors.

• now make a group and copy paste in extruded plan section.
• similarly copy the same for first floor plan.
• now for making staircase,make a region and extrude to the height adding 6" extra for every step
• select all and make a union and extrude the landing.
• copy paste the same for next stairs.
• select the staircase and paste in ground and first floor.
• for plinth level,extrude 2' downwards.
• for parapet wall,extrude the wall upto 3' height .
• for materials,select material browser from visualize panel or enter MATBROW.
• assign the specific materials.

• draw a circle of certain radius and extrude upto certain height.
• click on create camera and place of the extruded circle.
• name the camera and adjust the view.

• similar way provide distant light .
• speicfy view and enter rr to begin the render opertion.
• save the file to the desktop.

RESULT:
